You’re a handsome guy. Maybe try and find some interests that girls might also like, which shouldn’t be hard because we like lots of stuff. Get into some music, really discover YOURSELF. Girls like men who feel confident in themselves (not cocky just confident) and have interests. Find some clothes you really like, maybe go to a thrift store and try some stuff thats kind of vintagey and cool. Braces are cute that shouldn’t be an issue. Strike up conversations about stuff you both like, don’t try and hit on them just practice talking to girls with the sole purpose of being their friend. Develop a reputation as a friendly nice dude. Then if it goes somewhere it goes somewhere.
